We are the first country in history to deliberately make it harder for ourselves to trade with foreign countries and to deliberately throw away access to all sorts of information we need to ensure our own national security. We've thrown away our position as a 'bridge' between the EU and US and we've also tossed away a huge chunk of our businesses particularly in the financial markets.
What I personally fear is that once the co-vid pandemic is over we'll see the true consequences of Brexit in all their ugly glory. While I respect the result of the referendum I am absolutely certain that five years from now those who voted for it will realise they have deep cause to regret that. Personally I am afraid that our children and grandchildren will pay for our short sightedness.
